To ALL 'WHoM im MAY eoncnnn:

YBe it known thlat I, WILLIAM H. LACH, or Dorchester, in the county OfNOrfOlk, and State-of Massachuset ts, have invented certain Improvements in Scissors-Sharpeners, of' which'the following is a. full, clear, and'exact K, description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a perspective view of my'improved scissors-sharpener.

Figure 2 is a plan of the under side of the same.

Figure 3 is a transverseseetion on the line :v xof fig. 2.

The object of myinventiou is to provide, at a small cost, an implement of simple construction, bythe/use of which scissors'may be sharpened in a convenient and expeditious manner; and my invention consists in a pair of parallel blocks, provided with an inclined groove Afor the reception of a tile, the inclination of`which corresponds to that ofthe bevelled edge of the blade to be sharpened; one-of the parallel blocks being brought up toward theother by-a screw or screws for the purpose of making the width of the'opening between them vtoi correspond to thev thickness of the blade, a spring being also employed to. equalize the pressure communicated thereto by'the hand of' the opcrator,and tokeepythe bladeproperly guided as it isinoved over the file. A

To enable others skilled in the art tounderstand and ilsenly invention, I- will proceed to describe the manner in which Iv have carried it out. y

In the said drawings, A B are two`parallel blocks/each of which is provided with a longitudinal inclined recess, .forming a groove for the reception of a le, the inclination of which corresponds to that'of the bevelled edge of th'e blade to be sharpened thereon. The tile is kept-fronrsliding longitudinally,'when the blade is'drawn across it, by means of stops a a. The inner edge of each block A1B above the file is provided with a thi-n metal strip, against which the s ide ,of the blade is guided, the size ai' the opening c between the-blocks being readily adjusted t'o the thickness of the -blade by moving the block A tool' from that, B, by operating the screws D D. dis a bent spring, of the form seen in g.2,jthe contre ofiwhich is secured at 4 to the inner surface of the block A, while its ends `5 5 rest loosely upon the inner surface of the block B, and slide thereon, when the spring yields by pressing the twoY blocks together between the finger and thumb o f the operator. This spring serves to equally distribute the przessurerupon the sides of the 'li-lade, and to properly control it as it is drawn between the guides 6 across. the surface of the file. Instead of employing two screws D D for regulating the size ofthe opening e, 4one'only may be used, and pass through the middle ofthe block into that, B, without departing from the spirit of my invention. Y Y

` What I claim as my invention, and desin Ito, secure by Letters Patent, is'- The inclined le C, in combination with theparallel bloclgs A B, screw or screws D D, and spring d, all constructed, arranged, and operating substantially as and for the purpose set forth.
